Recycling maple plastic
Sugarmakers use a lot of plastic. Recycling is a much needed option to avoid disposing of tons of plastic each year.
Red maple (Acer rubrum) species page
Current inventory and climate change threat information for red maples.
Red maple as crop trees for maple syrup production
The often overlooked value of red maple trees for syrup production
Reduced sap yields from tapping into stained wood
What is the impact on sap production when your tap into an old wound? With tubing systems, it is almost impossible to know for sure. This presentation covers preliminary sap yield data from clean tap holes versus holes that hit brown wood.
Relating Spectrophotometer Readings to Visual Grading of Maple Syrup
Color grading of maple syrup is based on placing syrup samples within four or more categories based either on visual comparison to color references or measurement of light transmission with a spectrophotometer. With a spectrophotometer, specific transmission values are used as break points to divide syrup samples into color grades. The purpose of this report is to describe the lack of agreement between existing light transmission break points and visual grading and how this problem can be addressed.
Relationship between Tree Value, Diameter, and Age in High-Quality Sugar Maple (Acer saccharum) on the Menominee Reservation, Wisconsin
Guidelines for managing sugar maple-dominated forests by the single-tree selection method are well established and widely adopted. The forests of the Menominee Tribe in Wisconsin provide an opportunity to validate current guidelines by testing tree value and size/age relationships in forests that have substantially older and larger high-quality trees than can be found through the northern region. We harvested grade 1 sugar maple trees across a wide spectrum of ages and diameters, which we then manufactured into veneer, sawlogs, cants, and hardwood/pulpwood bolts to determine tree value.
Relationships Between Tubing System Component Age and Sap Yield: A Preliminary Assessment
Although a number of factors affect maple sap flow in vacuum tubing systems, it has become increasingly apparent that sap yields are largely a function of two major influences: vacuum level at the taphole and taphole and tubing sanitation.
Remaking Maple
Overview of new method of gathering sap from sugar maple saplings.
Research into Designing a Walnut Specific Spile
During the 2019 sap season, Future Generations University, with funding from the West Virginia Department of Agriculture, began a series of tapping studies on tree species other than maple. We tapped and made syrup from black walnut trees. We had trouble developing the expected natural vacuum on the 3/16-inch lines, even though they had plenty of slope. We assumed that the problem was related to vacuum leaks associated with a poor seal in the soft wood with the minimally tapered spouts.
